摘要

A gateway (103) determines whether or not voice information collected by a sound collecting device (102) needs to be subjected to voice recognition by a server apparatus (101), and only voice information that is determined to need to be subjected to voice recognition by the server apparatus (101) is transmitted by the gateway (103) to the server apparatus (101). The server apparatus (101) recognizes the received voice information, decides a control instruction, and transmits the control instruction to a household electrical appliance (104) via the gateway (103).
